The verdict in three sentences
An industrial parts distributor with 45,000 SKUs can launch an ERP-connected B2B site for 45,000 to 85,000 USD, delivered in 4 months. Two features drive profitability: search by manufacturer part number (with cross-references) and real-time stock pulled from the ERP. Done well, they remove about 30% of phone calls asking for price and availability, freeing your inside sales team for high-value deals.
The detailed budget for a spare parts B2B site
The technical catalog is the heart of the project. 45,000 SKUs with attributes, compatibilities and cross-references require data structuring work that is often underestimated. Here are the 2026 ranges for a distributor in the Miami area.
| Cost line (2026 estimate) | Price | Comment |
|---|---|---|
| Discovery, workshops and wireframes | 4,500 to 8,000 USD | 2 to 3 weeks |
| Technical catalog (attributes, filters, product pages) | 9,000 to 16,000 USD | Import and cleanup of 45,000 SKUs |
| Search by manufacturer part number and cross-references | 6,500 to 13,500 USD | Algolia or Meilisearch type engine |
| B2B customer accounts, net prices and discounts | 6,500 to 11,000 USD | Customer pricing from the ERP |
| ERP integration (stock, prices, orders, invoices) | 11,000 to 25,000 USD | NetSuite, Epicor, Sage 100, Acumatica or SAP B1 |
| Payment (card, ACH, net 30 account) | 2,200 to 4,500 USD | Stripe and customer credit |
| Testing, training, launch | 4,500 to 7,000 USD | 3 to 4 weeks |
| Total | 45,000 to 85,000 USD | 4 months |
For running costs, budget 220 to 550 USD per month for hosting and monitoring, 55 to 330 USD per month for the search engine depending on query volume, and 650 to 1,650 USD per month of ongoing development if you want a steady improvement pace.
ERP integration: what must sync and how often
A B2B site disconnected from the ERP quickly becomes a wrong catalog: outdated prices, items shown in stock while the warehouse is empty. The rule is simple: the ERP stays the master of data and the site displays it.
| Flow | Direction | Recommended frequency | Customer impact |
|---|---|---|---|
| Stock by warehouse | ERP to site | Real time or every 5 minutes | Reliable availability, fewer calls |
| Net prices and discounts per customer | ERP to site | Hourly | No more manual quotes for standard prices |
| New SKUs and product data | ERP or PIM to site | Daily | Up-to-date catalog |
| Web orders | Site to ERP | Immediate | Picking starts without re-keying |
| Invoices and delivery notes | ERP to site | Daily | Self-service download |
| Balance and credit limit | ERP to site | Hourly | Automatic block above the limit |
Cost varies mostly by ERP. A recent ERP with a documented API integrates for 11,000 to 15,500 USD. An older ERP exposing only file exports or a SQL database needs a custom connector, closer to 18,000 to 25,000 USD.
Search, the feature that makes or breaks the site
A maintenance buyer types 6205-2RS, SKF 6205 bearing, or the original part number printed on the worn component. The engine must tolerate typos, handle cross-references between manufacturers (SKF, Timken, NTN) and answer in under 200 ms. Without that, the buyer picks up the phone, and your investment does not reduce your team's workload.
Mini case study
Maria, owner of an industrial parts distributor in Miami (bearings, power transmission, pneumatics), receives about 180 calls a day, 60% of them simple price or stock requests. Her 6 inside sales reps each cost 62,000 USD a year fully loaded.

She invests 70,000 USD in a B2B site connected to her NetSuite ERP. After 6 months, phone inquiries drop by 30%, or 54 fewer calls a day. At 6 minutes per call, that is 5.4 hours a day, about 0.7 full-time equivalent, roughly 43,400 USD a year of sales time redirected to prospecting.
The site also generates new orders from customers who buy in the evening or on weekends: on 10 million USD of revenue, if 1% extra revenue is captured at a 28% margin, that is 28,000 USD of margin. Annual gain: about 71,400 USD, minus 10,000 USD of running costs. Payback in about 14 months.
FAQ
Do we need a PIM for 45,000 SKUs?
Not necessarily at first if the ERP holds clean attributes. Beyond 20 to 30 attributes per family or several languages, a PIM such as Akeneo adds 9,000 to 22,000 USD but makes product data reliable.
Can we show different prices for each customer?
Yes, net prices and discounts sync from the ERP every hour and display once the customer logs in. Anonymous visitors see a list price or a request-a-quote button.
Which platform fits this type of site?
For 45,000 SKUs and customer pricing, Adobe Commerce Open Source, BigCommerce B2B Edition or a custom build are the most common, between 45,000 and 85,000 USD. Shopify Plus works if pricing rules stay simple, with a 2,300 USD monthly subscription.
How long until we go live?
Plan 4 months on average, including 4 to 6 weeks for ERP integration. Catalog data cleanup is the leading cause of delays, so set aside 2 to 3 weeks on your side.
Does the site handle quotes for special parts?
Yes, a cart can be turned into a quote request for made-to-order SKUs or large quantities. The module costs 3,300 to 6,500 USD and sends the request to the ERP or CRM.
